Welcome to <BABLR/>

Something for everyone...

Support new languages after the fact
Define custom tools, e.g. type-aware linting
Define tools that can work on infinite inputs and those larger than system memory
Interoperate naturally
Developers want to use trusted tools when working on new languages

Existing platforms use a mix of tooling like: LSP, ANTLR, Tree-sitter, TextMate
Our platform consists of:

CSTML: An untyped document format akin to XML/JSON
BABLR: A parser-based schema validator for CSTML documents
Paneditor: A web UI for semantic coding built on BABLR

So we can support multiple UX modes:
- Voice gesture
- Terminal editing
- Online collaboration
- Interactive devtools

Define languages in a way that supports tools that haven’t been made yet
Create new languages by extending existing ones

Designing tools that make it easy to:

Parse left to right (like people do)
Perform arbitrary lookahead
Maintain balanced spans
Generate helpful parse errors
Regex matching
Just-in-time tokenization
Skip the build step
Get the most out of Devtools
